Be it known that I, KENNETH MURPHY, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Show-Card Exhibitors; and I do hereby declare the following to be a full, clear,and exact descrip-' tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in show card exhibitors, and the principal object of the invention is to provide a device which is particularly adapted for use in street railway cars, in order to increase the advertising space therein.

Another object of the invention is to provide an attractive device which is designed to change the advertising card at intervals, thus presenting a new advertisement in the same space. i

A further object of the invention is to provide a device composed of a series of exhibiting units arranged to be driven from a single power shaft extending through the whole.

With these and other objects in View, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure l is a front elevation of three exhibiting units, showing the central one with the advertising cards removed to illustrate the details of construction;

Fig. 2 is an enlarged vertical sectional view illustratingin detail the transmission gearing by which the device is driven;

Fig. 3 is a vertical sectional view smnlar to Fig. 2, illustrating in detail the method of operating the device by hand for facilitating the positioning of the advertising strips in place;

Fig. 4 is a front elevation of one of the advertising strips;

Fig. 5 is an enlarged fragmentary view of the rear side of the adjoining edges of the strip; and

Fig. 6 is an edge view of Fig. 5.

Fig. 7 is a horizontal sectional view through the device; and

Fig. 8 is an enlarged detail view of the belt guide.

Referring to the drawings, 1 designates the upper forward frame bar of the device,

' extends through all of the units while the numeral 2 designates the lower forward frame bar. These bars support a housing 3 at their rear sides and extending rearwardly from the bars are the partition walls-1 arranged in spaced parallel relation. The dividing bars of the device are designated by the numeral 5 and each bar is provided at its lower end with a tongue 6 which engages the rear face of the bar 2, While the upper end of each of the dividing bars has attached thereto a plate 7 through which a cylinder 8 rotates, which cylinder is provided at its rear end with an arm 9 for engagingin therear of the upper bar 1, while the cylinder projects through an aperture 111 the bar 5 and may be engaged by a suitable key by which the device is turned. It will thus be seen that the bar may be readily moved-when it is desired, to change the advertising matter.

Mounted in each unit at its upper end and adjacent the upper frame bar, is a drive roller 12 while a similar roller 13 is mounted at the lower end of the unit adjacent the bar 2. The roller 12 is provided with a pinion 14, which meshes with a gear 15 which in turn is driven by a pinion 16 meshing with the gear 17 the hub port on of which is provided with a gear 18 meshing with the segmental drive gear 19. Mounted on the main drive shaft 20, which and is provided at its end with a suitable gear 21 which meshes with a pinion 22 which is driven by a worm gear which meshes with a worm carried by the shaft of the driving motor 23. In addition to the rollers 12 and 13 within the housing 3, there are provided a plurality of idlers 2 1 over which the drive belts pass. As illustrated in F ig. 1, there are provided three drive belts designated by the numeral 26, and each of said belts is provided with a hook 27 on which the exhibiting strip is secured.

In order to hold the belts in proper spaced rela ion, suitable belt guides 28 are provided with the guide fingers 29.- The exhibiting strip is designated generically by the numeral 30, and consists of strips of fabric 31 having attached thereto, the advertising cards 32, the side edges of which are provided at spaced intervals with transverse slots 33 through which the laces 34 extend. One of the end strips 31 is formed with openings to receive the hooks 27 and it will be evident that in use the openings re ceive the hooks 27 and the exhibiting strips are threaded over the various rollers by means of the belts. Slipping of the belts on the drive rollers 12 is prevented by the pins 12 carried by said rollers.

In order to set the belts for receiving the exhibiting strip a suitable sprocket 35 is attached to the end of the roller 12 opposite that having the pinion 1e thereon, and passing over said sprocket is a drive chain 36 which in turn passes over the sprocket 37 provided with a crank handle 38 by which the same may be turned by hand. It will thus be seen that when it is desired to place the strip on the belts, the crank 38 is turned until the hooks 27 appear within the exhibiting space bounded by the bars 1, 2 and 5, whereupon the exhibiting strip is placed on the hooks and the crank 38 turned until the two ends of the exhibiting strip are brought together within the sight opening, whereupon the same are laced by passing the laces 34: therethrough and tying the same at the rear as illustrated in Fig. 6, after which the motor 23 may be set in operation and it will be seen that the mechanism will be driven so as to keep the strips constantly moving before the sight opening, thus bring ing the cards 32 into view in succession.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

What is claimed is An exhibitor of the class described, comprising a housing provided with a sight opening, rollers mounted within the housing above and below the sight opening, belts passing over said rollers, hooks carried by the belts, an exhibiting strip composed of a series of spaced fabric strips and advertising cards positioned between the strips, one of said fabric strips provided with hook-receiving apertures, lacing cords passing through the edge portions of the advertising cards and the fabric strips for detachably connecting the same together, and means for rotating the rollers to cause the belts and exhibiting strips carried thereby to pass about the rollers.

In testimony whereof I affiX my signature in presence of a witness.

KENNETH MURPHY.
